The vice chancellor, his secretary, and Khera were abducted in Srinagar by the Students Liberation Front in April 1990, who demanded three jailed terrorists be released. However, the then Governor Jagmohan rejected the demand, following which all the three captives were killed.

While the body of Khera was found at Batmalloo area, the bodies of Mushir-ul-Haq and his secretary were found in Padshahi Bagh, both of Srinagar, five days after their abduction.

The Central Bureau of Investigation (CBI) was asked to investigate the case, but even after 19 years, nothing could be proved against the accused.
